IMPROVEMENT IN WATER-PROOF CELLARS..

Specification forming part of Letters Patent No. 113,328, dated April 4, 1871 Reissue No. 7,920, dated October 23, 1877; Reissue No. 8,387, dated August 20, 1878 applicatioitliled August 12, 1878.

description thereof, which will enable others skilled in the art to make and use the same, reference beinghad to the accompanying drawing, forming part of this specification.

This invention relates to a new and useful improvement in the construction of sanitary and water-proof cellars, cisterns, vaults, reservoirs, and all underground apartments for whatever purpose, whereby bottom and walls of such cellars and other places above mentioned are kept in a sanitary condition, and are made perfectly impervious to water.

The invention consists in the use of successivelayers of roofing-felt and asphaltic or roofin g cement, associated with a layer of concrete or hydraulic cement, combined with gravel or other layers of equivalent material, applied as hereinaftermore fully described.

lhe accompanyin g drawing is a vertical section ,of cellar with the bottom and walls constructed according to myinvcntion. v My invention is not limited to the particular combination of the materials heretofore mentioned and used as hereinafter set forth. I

prefer, however, the following combination and use of'such materials as is contained in the accompanying drawing and following description of the same and direction for carryin g out the same.

In the particular combination referred to, A represents a cellar-wall, on the inncn side of which I commence to place my waterproof layers of cement and feltin g. B represents the felting. B also represents the layers of roofing or asphaltic cement. 0 represents an inner wall of brick, stone, or wood, sufiiciently strong and substantial to withstand any expected pressure of .water from without. D is a layer of hydraulic concrete between the ocment layers and the wall C. This layer of hydraulic cement may or may not be employed, as may be deemed advisable.'

v In carrying out my invention according to theparticular combination of materials shown in diagram, and herein described, I commence with the bottom, which I prepare by smoothing it off and making a tolerably even surface by means of concrete or otherwise, and then apply alternate layers of roofing-cement and roofing-felt or of equivalent material. In this manner I apply four layers, more or less.

To enable the bottom thus formed to withstand the upward pressure of water, I'weiglr down or ballast the bottom in any convenient manner. The walls of the cellar, cistern, &c. I construct in a similar manner.

The surface, whether of stone or of other material, having been made sufficiently even, the cement is first applied, and then successive layers of the felt and cement,.with the inner wall or bulwark of stone, brick, or wood, which inner wall is, placeddirectly against saidlayers of felt and cement, and anchored to'the' outer wall at the top, and either with or without the intervening layers of hydraulic concrete, as may be deemed best. At the angles or corners of the-cellar or like place the layers of the felt on the bottom and on the sides may lap past each other, if desired, so that the wall and the bottom may be firmly united and a tight and water-proof joint be insured in every part.

As already stated, I do not limit myself to the particular combination and application of such materials as herein dcscribed. The especial and most useful feature ln my invention is the use of the layers of roofing-felt and the layers of asphaltic or renting cement.

The adjacent layers of concrete or cement,

of kinds commonly known to and-used by masonsfor such purposes, while to some degree impervious, are mainly for securing solidity and'weight to the structure. The layers of roofing-felt and asphaltic cement are most etfeetivewhen alternated and having the masonry or concrete or cement mainly superimposed.

Aprime advantage of these layers'of roofingfelt and asphalt-ic or roofing cement, however.

used or associated, is the disinfecting quality,

,as well as water-repellent property of the same, there being hardly so powerful a disinfectant known for such uses as these layers furnish. It has long been greatly desired to find some means of resistin g and counteracting not-only the moisture, but the gases and malarial inand protected and having the advantages as finences and other causes of disease so freabove set forth.

The most essential feature of my invention is the use of the layers of roofing-felt and of asphaltic or roofingcement, as above described,
